rlhis invention relates to signaling devices for use on vehicles, motor boats and` elsewhere to give warning of an intended change in the direction of drivingor of an intended stop, and it has for its object the production of a signaling device for the said purpose which shall be inconspicuous or substantially invisible when it is displaying norsignalbut which shall, when in operation, cause its'slgnaling member `to be distinctly displayed so as to bevisible from substantially all directions. Further objects of the invention, which will be herein disclosed as applied to an automobile, are to produce a signaling device of the character stated which shallbe dependable in use, simple and inexpensive in its construction and easily applied either as stock equipment ofa new car or as anattachment to a car already in use; to provide means readily accessible to the lhand of the driver of the vehicle for setting the signal to vindicate eithera right or left hand turn', and

means associated with the brake ,pedal Vfor setting the signaling device to indicate a j stop; to provide connections withthe intake manifold of the engine cylinder for producing a suction 4upon the signal operating means whereby the latter is' operated automatically from said manifold, and to provide means for illuminating the device so that the signaling memberfthereof will be conspicuously displayed at night. f

While signaling devices for accomplishing the above stated objects may be embodied in various specific forms, that shown in the accompanying drawingsis our preferred embodiment, although it is to be understood that the claims appearing herewith are not intended to be limited to the specific structure shown any farther than isr'equired by their express terms. i

Aswill be seen from Figs. 1, 2 and 3, the

signaling member 20 is pivotedat 21 in a suitable box or casing 22 which is connected to that front post 23 of the automobile body yfwhich is at the left hand side ofthe driver of the automobile.

As therein shown, this box or casing is attached to said post on its kfront side where it is inconspicuous, and is invisible from the rear of the machine.` lnV Vvapplying my invention to cars already built,

this is the preferred location of the signaling device; but when the latter is made a partof the regular equipment of the vehicle, it is preferable to have the casing 22 embedded within the said frontl post in its'left hand face, as is indicated by the dotted lines in Fig. 3. l

The signaling member 2O is an elongatedV box-like structure, the front and rear walls of which are composed of suitable transparent material, such as glass or Celluloid, as

indicated in Fig. 19 at 20'l and 20h. Within vthe box-like signaling member is an electric lamp 20c, controlled, as hereinafter specified,

in sucha manner as to illuminate the signallbeing reciprocated in a vertical direction by means hereinafter described. Each of` the elements 25 and 252L is formed on two radii,

as shown, so as to provide a hook-likeprojecytion at 30and 30a, respectively, the projection 30"on the segment 25 being farther advanced toward `the right than is the corresponding vprojection 30a on the other segment. These projections co'operatewith the dogs shown in Figs. 9 Vto 12 and form stops determining the extent of rotation of `the gear' segment 28 and the 'signaling member 20 ywhen moved by the rack 29. These'dogs, designated 31 and '31, respectively, are journaled upon a transverse shaft or` pin 32 which is supported within the side plates 27, and they are each Athe rods 40v are connected.

provided with a laterally projecting nose 32,

32a, the latter each having a rounded surface 33 in the plane of the respective elements 25 and 25a and adapted to engage the hoo-lrlike projections 30 and 30a thereon to arrest the rotative movement of the gear segment 28 and the movement of the signaling member Y2O. The dogs' 31 and31a are independently operable from means within convenient reach v and control of the driver of themachine.

TWhile various devices may be satisfactorily employed, we have chosen to show the pivoted levers of Figs. 2O and 21.k Referring to these figures, 34 represents al portion of the instrumentboard of the automobile, at the inner face of which there is attached a plate 35 supporting pivoted levers 36 and 37, thev levers extending'through the instrument board and into the automobile body vwithin convenient reach of the driver. The lever 36 is shown in its normal position, while the lever 37 is shown tilted upwardly at its rear or operating end and downwardly at the end in front of the instrument board. Each of these levers lis connected, through a rod 38 and a rocking lever 39 to' a vertically extending rod 40. The connections just referred to are shown in the` sectional view, Fig. 4, and, in part, in Fig. 18.v Fromthe latter view it will beseen that there are two `yof the pivoted levers 39 towhich j These vrods are extended upwardly through suitablerpacking glands 41 in the valve block 42' and .into position for lifting rball valves in said valve block, all as will be described hereinafter. each of the rods there isa head or enlargement 43 upon which'reststhe lower end ofk Upon other upwardly extending rods 44. There are two: ofthese rods .44, one for each of the` levers 36 and 37 on VYthe instrument board, and

v.they are connected at their upper ends with the dogs 31 and 31a, respectively. From this it will be understood thatv when one of the levers 36 or 37 is'li'fted lby the operator the correspondingrod 44 will likewise be lifted to U turn the respective dog`31, 31%, into position to bring its nosey 33 into the path of the hooklike projection 30, 30a, of the elements 25, 25.

Thesev dogs are thus set to determine the extent of movement of the signaling member 1 i' f 20 and the character of signal given thereby.

'lhe rack 29V for turnin-gthe gear segment '281s suitably guidedvat its upper end and 1t 1s reciprocated by a piston 45 within a cylthere is connected a tubular member 47 which is a screw threaded on its Vupper end, as shown in Fig. 4 This tubular member is extended through a hole formed in the cowl 48 of the automobileY and is held in position by nuts 49 which are yscrew threaded-'upon said member(4 Between the nuts andtheco'wl 48, the

member is surrounded bytapered washers 50, i of compresslble material, having their tapered surfaces suitably formed to engage with the 'inder 46. To the upper end of the cylinder 4cowl 48 and clamp the same securely when the nuts 49 are screwed into position. The

tubular member 47 is also attached tothe l sition of these balls is selectively controlled from the levers 36,37 within the car or from the brake pedal, as will be described.

The pipe 5l from the engine manifold connects with a bore 52 in the valve block 42, which bore extends downwardly within the block and connects with a horizontal bore 53. This bore 53 is projected into the block from the left hand side, as shown in Fig. 4, terminating at its right hand end in a .similarly constructed manifold 54 adjacent the cylinder 46, said manifold 54 being best shown in Fig. 7 The outer end of each of these manifolds is closed by a suitable pluO so as to make it air tight. Adjacent the p ug in the manifold 53, the latter connects with another manifold 55, which is best seen in Fig. 8, although it appears in dotted lines in Fig. 6. Extending downwardly from the upper surface of the valve block 42 are four bores lconstituting valve chambers, the outer end Vof each of these bores being closed by suitable screw plugs. On that side of the block adjacent the cylinder 46 there are three of these valve chambers and screw plugs in a row, as shown in Figs. 6 and 7. In the latter' figure the valve chambers are designated 56, 57 and 58 and the screw plugs closing the latter are designated 59. These valve chambers are connected with one another through manifold passages 60; and the center chamber 57 is connected with the top of the operating cylinder 46 through a iuid passage 61. The inner or lower ends of each of the valve chambers is conical, as shown, to form seats for balls 62. When these balls rest upon the seats they close passages 63 leading to the manifold 54. When any one of these valves is lifted it `establishes comm-unication between pipe 51' and the space above the piston 45 of the cylinder 46, whereby the piston is drawnupwardly to operate the signal, the .piston being connectedwith the rack 29 through the piston` rod6`4.V The rods 40, hereinbefore' described, -eXtend upwardly through the valve block beneath the balls in cha-mbers56` and 57', respectively, the .said rods being suitably packed to prevent leakage by the glands 4l, previouslyre'ferred to. The ball 62 inthelchamber 58 is not 'controll'edby the hand levers 36', 37, but' byl the brake pedal 65, shown in Figlr22. In applying the brakes, this pedal is moved in the direction of the arrow. Connectedl tothe pedal below its pivot v66, as at the point 67,

is a yielding member 68 which leads to the arm 69 of a bel-'l crank which is pivoted at 70, the other arm 7l of the crankbeing connected to a rod 72 which extends upwardlyinto the valve block 42v beneath the ball 62 in the valve chamber. 58. Therefore, when the brake lever is operated, the bell crank is rocked. to lift its rod 72and its corresponding ball valve i 62 to establish connectionxbetween. the engine manifold and the upper end of the cylinder 46. Whereas the rods 40 operate their correspondingrods 44` to control the dogs 31, 31a, thus to arrest the signaling member 20 to indicate the right and left-hand turns,

the rod 72 has no corresponding rod 44, and

when it lifts its ball valve .62 there is no dog to arrest the movement of the signaling member, which continues its movement until it contacts with thel frame 27 at the point 27EL in Fig. 4. When in this position against Vthis contact point, the signaling member indicates that the car is to stop.

It wlll thus be seen that, when any one of the ball valves 62 is lifted, the piston 45 is caused to rise to operate the signaling member to display a signal correspondingto 'the particular ball valve that has been lifted.

In addition/to the three valve chambers 56, 57 and 58, the block 42 is provided with a fourth valve chamber173, the same having a ball valve 62a therein. This valve is adapted to rest upon a seat like those of the other chambers and to be lifted by a rod 74 which corresponds in structure and arrangement with the rods 40. Thisbal-l valve 62a controls a passage-75 which leads to thecylinder 46 at its lower end. beneath the piston 45. Assuming that thepiston has been raised. within the cylinder, it is returnedto the position shown in Fig. 4 by lifting theba'll' valve 62a, which establishes suction from thel engine manifold through the pipe 5-1, passage 52manifolds 53 and 55 to the valve chamber 73 and thence, through the passage 75, to the cylinder 46, thus to draw clown the vpiston and return the signaling arm to its neutral or concealed position. No matter which oneof the ball` valves 62 may be raised, the' valve 62a must, at the same time,.beseated,Y as otherwise there would be a suction upon both ends of 'the4 cylinder. Conversely, whenever the valve 62'a is raised, any valve 62 which had been lifted must be seated. i

In order to obtain this alternate movement of the return valve `62au and the operating valves 62, the rods 40 and 7 2-are'caused'to rock a lever plate 76, which` is pivoted on '9" and 80 upenone @fits 3 side edges anda` single set of prongsvS'l. on

its opposite side edge. This latter. set of prongs straddles the rod 74, the latter being provided-with.conical'nuts 82 on opposite sides of the prongs '81 so that the plate 76 causes the ro.d.74,to inove up and down whenever the plate is rocked by either of the rods y40 or the rod 72. To facilitate the return of to the right hand, the operator lifts the lever 36 which simultaneously sets they dog 3l?L into position for arresting the signaling member in its upwardly inclined position, shown in F ig. l, and also lifts the valve 62 to establish communication between the engine manifold and the Lipper part of the cylinder 46. rlhe same movement of the lever 86 rocks the lever plate 76 to Vlower the return valve 62a so as to make the suction above the piston effective. .Having made the 'right hand turn, the operator returns the lever 36 to its normal position, thereby lowering` the ball 62 which yhad been raised and rocking the lever plate 76-to raise the return valve 62a, thereby establishingconnection between the engine manifold and the bottom part of the cylinder 46 thus to draw the'piston downwardly and restore the-signal member to its neutral or invisible'position. lf the driver should neXt Vdecide to turn to the left he operates the lever 37 with like effect and then returns it to 'normalposition, which again restores the parts, as before described. If he should decide to stop the car and so applies his brake, he will rock the leverplate 76 to lower the ball valve vGZffand Vraise the valve inthe chamber 58, thus to cause the piston to move upwardly. But in this case no dog has been set and thev signaling member willfcontinue to turn until it engages with the stop 27a,` as

has'been described. Upon the release of the Vbrake pedal, the lever plate 76 is returned to normal which causes the piston to be drawn down toi-the bottom of the cylinder, thus to position.

restore the signalingmember to its neutral Owing tothe fact that brakes become worn, it becomes necessary to move they brake pedal ldifl'erentvdistances in setting the brakes. We

have, therefore, provided theyielding connection 68 between the -brakepedaland the bell crank-69. To prevent the Ybell crank from being rocked too far, we further provide a leads to the battery, not shown'.

tion Yirrespective :In orders toil'luminat'e the sign, anelectric current is supplied. through a wire 85 which This wire ka binding post 86, with a spring contact 87,

the latter Ahaving a metallic pin 88 which is pressed toward the left, as shown in Fig. 5.

The positionof the pin 88`is shown by the dotted circle 88 in Fig. 4, from which it will be seen that, vwhen the parts are in their normal positions, the pin bears upon an insulated member 89 which is suitably mounted rupon the adjacent segment 25a, said member 89 appearing in side elevation in Fig. 17.

Normally, therefore, this pin bea-rs upon the Y member 89. of insulating material and no curvrent canflow. Substantially as soon, however, as the gear segment 28 with the seg-v mental element 25a moves fromits normal position, counter clock-wise as shown in Fig. 4, the metallic pin 88 moves off of the insulating member 89 and onto a conductor 90 which is suitably attached to the side of the element 25a but is properly Vinsulated therefrom, as will be clearly understood. The conductor 90 is bent about the shaft 26 and concentric therewith, so that, no matter how far the gear segment may turn, the pin 88 will remain in contact with this conductor. The latter is carried upwardly into the base portion 91 of the socket 92 of the lamp 20. This lamp is suitably grounded to the frame of the signaling device for the return of the Current to the battery, as will be understood.

Vhenever, therefore, the signal member isV turned from its normal or neutral position, the lamp 20C is lighted to illuminate the signal which thus becomes effective for use in the darkness. f

The piston 64 passes outwardly through a stuffing box 93 in the cylinder head 94.y EX- tending through the headare a plurality of screws 95, the inner ends of which are threaded. into a follower plate 96. By turning the said screws, this plate may be drawn toward the head 94 to compress packing 97 into the joint betweenl the vhead and the cylinder walls. The follower plate supports the packing about the piston rod also, but this pack-` for engaging the said element, means under control of the operator for moving said dog into position to engage the said arresting element, and means loperable upon the Vreturn of the kdog to normal position for automatically returning the signaling member to its normal position.`
